FAQ

How to measure the influence of high-temperature performance of the products refractory in the formation of the liquid phase.
Generally how can do high-temperature performance to measure how much liquid may affect hot bending strength rul refractoriness levels of high temperature creep?
What things and cement mixed can act as refractory?
Cement acts as cementing material. Itself works by refractory aggregate and stir the refractory material for its gelling refractory aggregate both should be fire-resistant.
Who can tell me the properties and classification of insulating refractories?
Insulation materials can be classified according to service temperature, production process and application fields.
What are included in wall fireproofing material?
External wall thermal insulation materials are divided into A and B according to combustion level. Grade A is incombustible material, while grade B is combustible material. A few years ago, fires in CCTV building and Shenyang hotel resulted from grade B material. Currently grade A is usually used, and some are even cheaper than the grade B material. Grade A is roughly divided into insulation mortar, phenolic board, rock wool board, foam cement board, etc. Insulation mortar is quite good. It is easy and convenient to construct, has low cost, but the production is too simple and it is easy to fake.
Where is the sizing nozzle for refractories? Just enter the line, master into!
Hua Heng refractories in the industry reputation is good, especially in the Southern small steel sales are among the best!
what kind of fireproof materials is used for high rise buildings?
Recommended thickness of 1mm or more # 304 stainless steel, refractory, corrosion-resistant, easy to clean. closed balcony of high rise buildings use thickened manganese, aluminum profiles. You can also use plastic steel window, solid wooden windows. Mg-Mn alloys have excellent weldability and corrosion resistance, unstressed corrosion tendency. Mechanical properties are not good enough, the ultimate strength of 210 ~ 280MPa.
What are the fire resistance ratings of the glass partition?
When the inner structure of the system is steel structure, the fire resistance of which is 30 mins, 60mins or even longer. The partitions in the usual sense are walls that have a distance to the ceiling. The fixed partitions directly touches the ceiling are partition walls which should be required in accordance to the specifications of walls. If the partition is far from the ceiling, the fire protection requirements are relatively low. Partitions which combustion performances are no less than B1 level are safe enough, while partitions of places such as shopping malls have to reach A-level in terms of combustion performance.
What kinds of refractory will be used in kiln of sintering ceramics?
High alumina brick, clay brick, insulating brick and silicon carbide plate.
